I have just installed Ruby Enterprise Edition and am installing some gems for it. Stock Ruby 1.8.6 is also installed on the server.
I have added /opt/ruby-enterpri
/opt/ruby-enterpri
A solution I used to a similar problem is to set up an alias to your REE gem command.
I.e.
alias reegem='/opt/ruby-enterprise-1.8.6-20090201/bin/gem'
